The the production processes of Auto water pump impeller

1.IQC:check the DOB,the component should accord with  "GB699-1999".The surface is without bubble,flaw,scab,crack,impurity and obvious scarification,it can't be have layer.The sickness of steel plate is 1.5-0.04mm.

2.Store:put-in-storage:make the storage mark and quality state mark.Used base plate or shelf to separate steel plate from floor,ensure to moistureproof.

3.Picking:follow up FIFO policy,ensure the item and quatity agreen with material requisition.It should handle with care.

4.Process :(1).shear(The size is accord with "cold stamping process card".) → (2).blanking → (3).stretch(free of dents) → (4).profiling(without cinc mark) → (5).scrap edge → (6).forming → (7).nubbincutoffmachi → (8).burring → (9).checking(without cinc mark or burrs or others) → (10).finish(galvanized) → (11).checking(surface is without phanic coating defects,and the coating is clean,and not damage.The surface is bright.It quickly rub 10-15s with each othre,the coating is without bubble or metal peel.)

The feature of Auto water pump impeller

1. Workpiece surface smooth, the transition smooth without cracks, creases and other defects.
